A control scheme for controlling power sharing among a plurality of parallel connected DC voltage sources is disclosed. Each of the DC voltage sources in parallel connection is an independent DC power system, which can be an suitable DC power supply that can provide power to a load. By way of example, the present disclosure describes a DC power system that includes a power source, an energy storage unit and a triple active bridge converter that provides power to the common load. Each independent DC power system has its own controller that shares a DC bus with the other DC power system controllers. Each controller executes non-transitory instructions to provide a reference voltage V* to its respective independent DC power system and implements a control scheme that changes the voltage reference to ensure that each independent DC power system only provides a certain share of the load current/power.
